Serialise/deserialise a ProcessInstance

[ateodorescu]

The current implementation of serialisation/deserialisation is not really useful if you want to save process instances in a database. You can't store them serialised because you can't do any kind of report on the process data not to mention sorting/filtering data in a work list..

In a database one would save the following data for a ProcessInstance:

• id, name, idProcessDefinitionVersion, process data
• all tokens available
• all work items available and the activities they are linked to.
• all sub-process instances and the activities they are linked to (this is not implemented yet)

So the ProcessInstance class could be modified to serialise/deserialise only the data described above. Anyone agrees to this? Anyone working on this already?
